[R] xyplot and lsegments

Hi, How might I use xyplot to plot segments where the segments are in the input data? (ie a directed acyclic forest). Here's an example in base graphics: n = data.frame(id = c(1,2,3,4), parent = c(0,1,2,2), value = c(5,5.5,7,3), date = c(1,2,3,3.5)) plot(n$date, n$value) do
